Meckel diverticulum is a remnant of the omphalomesenteric duct. It often contains ectopic gastric or pancreatic tissue and can become inflamed, mimicking acute appendicitis.
Only about 50-60% have ectopic gastric mucosa, and therefore it is not excluded based on the negative T99m pertechnetate scan. In fact, one could argue ifwhether it was even necessary based on the classic CT appearance with normal appendix (if it would go to the OR with a negative or positive scan, why did they do it?!).

Surgery confirmed the Meckel diverticulum, which was removed.
